GAS HEATING BURNER.

SPECIFICATION forming part of Letters Patent No. 408,073, dated July 30, 1889.

Application filed February 8, 1889.Y Serial No. 299,168. (No model.)

To all whom it may concern: l

Be 1t known that I, HAROLD J. BELL, a citizen of the United States, residing at Gloucester City, in the county of Camden and State of New J erscy, have invented new and useful Improvements in Gas Heating Burners, of which the following is a specification.

This invention relates to a blow-pipe attachment for heating steam-boilers and furnaces io by the combustion of gas; and-it consists iu the construction and combination of devices hereinafter described and claimed.

In the annexed drawings, illustrating the invention, Figure 1 is a side view of a gas pipe, tube, or conduit inelosing an air tube or conduit, which is connected to the gastube by a number of compound tubes or burners, this construction being especially adapted for the heating of furnaces. Fig. 2 2o is a vertical cross-section of the saine. Fig. 3 is a sectional elevation of an arrangement of burners and supporting-plates forming conduits or passages for gas and air, in which the partsare especially adapted for the heat- 2 5 ing of steam-boilers. Fig. 4is a cross-section 0f a steam-boiler with my improved blow-pipe heating attachment applied. a

The numeral 1 designates the gas-conduit, and 2 the air-conduit. These conduits are 3o connected at suitable intervals by laterallyprojecting compound burner-tubes I3, constructed to permit the passage oi' a central air-jet and a surrounding annular gas-jet, in the manner hereinafter described.

In Figs. 1 and 2 I have'shown a construction that is particularly adapted for the heating of furnaces, though useful also for other purposes. In this construction the gas-conduit consists of an outer pipe 1, in which an 4o air-conduit or inner pipe 2 is inclosed. These pipes are tapped laterally at suitable int-ervals and in the same line for the attachment of air-nozzles 4, which have a screw-threaded connection-with the inner pipe or air-conduit and project through the outer pipe or gas-conduit.

Each air-nozzle is provided within the gasconduit and near the air-conduit with an an- 7, that comin unicates with the gas-conduit.

nular shoulder 5,011 which rests a bushing (i, that is screwed into the outer gas-pipe 5o around said air-nozzle. This bushing 6 has a central perforation by which it is enabled to surround the air-nozzle, and on one side it is provided with a longitudinal gas-passage Above the bushing G, resting thereon and surrounding the air-nozzle 4, is a burner cap or tip 8, which is provided internally with a perforated disk 9, having a central screwthreaded engagement with the air-nozzle, by 6o which it is thus supported. In the upper end of the cap or tip 8 is a gas-exit 10, that surrounds the exit end of the air-nozzle, thus providing for the annular gas-flame having a central air-supply to promote combustion, and it will be seen that as the air-nozzle 4 is supplied with air under pressure it will act as an injector or blow-pipe to increase the intensity of the gas-flame.

In Figs. 3 and 4 I have shown a eonstruc- 7o tion in which the blow-pipe burner-tubes 3 are attached to and supported by plates 11 and 12, inclosed by an outer plate 13, all of which plates are supported by or in proximity to a steam-boiler 14 which they partly 75 surround, in such a manner as to form a gasconduit 1 and an air-conduit 2, both of which communicate with burner-tubes 3, constructed as already described. This construction ot gas-conduits is particularly adapted 8o for attachment of the burners when. employed to heat a steam-boiler. The plates 1l, 12, and 13 are stayed and connected by sleeves or tubular stays l5 and bolts 1G at required points.

By providing suitable cocks (not shown) for the gas and air conduits it is obvious that the supply of gas and air can be regulated as required.

What I claim as my invention is- 1. 'lhecombinatioin with a gas-conduit and an air-conduit, of au air-nozzle 4, communieating with the air-conduit and projecting laterally through the gas-conduit, a bushing G, su pported by the gas-conduit and surrounding the air-nozzle, said bushing being provided with a gas-passage 7 and a burner-tip 8, surrounding the ail-nozzle on the outside of said bushing, substantially as described.

2. The combination, with the plates 11, 12, and 13, forming a gas-conduit and an air-conduit, of stays 15 and bolts 16, connecting said plates, and a. number of laterally-projecting burners 3, each having a central air-nozzle 4 and a, surrounding` burner-tip S, substantially as described. 1o

In testimony whereof Iax my signature in presence of two witnesses.
